Digital Broadcast Production Console
the Device Status screen provides a
graphical overview of the status of all
devices configured on the network.
Each port has an indicator, which will
“heartbeat” (flash green) to indicate that
the unit is running and can be reached.
If the device is not “heart-beating” then it
cannot be reached and its graphic will be
greyed out.
In the case of Hydra I/O Racks using
both ports (for redundancy), each port
will have its own heartbeat indicator. The
preferred port will be highlighted. If a port
is not heart-beating, its indicator will light
red (But the device could still be in use
through the other port).
deVICe StatuS
If neither port is heart-beating, then the
device is no longer available, and it will
appear greyed out on the screen.
If the device does not appear to be heart-
beating, but it is not greyed out, then the
console can access the device, but the
PC cannot. This situation could arise
in redundant systems, where the PC is
connected to just one of two switches,
and the connection between the switches
has failed.
The PC will only be able to “see” the
devices connected to the same switch as
itself. As the console will be connected
to both switches, normal operation can
continue.
